Our country is no longer a country of laws. Laws are only as good as they are enforced. The SCOTUS, the DOJ, the FBI, and congress have openly abdicated any constitutional responsibility to provide checks and balances to reign in the abuses we see posted to HN every day.
I disagree with them, but that isn't relevant.
